RF electrical parameters
This section summarizes the operating and measurement conditions, and the DC and AC
characteristics of the device in RF mode.
The parameters in the DC and AC Characteristic tables that follow are derived from tests
performed under the Measurement Conditions summarized in the relevant tables. Designers
should check that the operating conditions in their circuit match the measurement conditions
when relying on the quoted parameters.
